Alatubah jenis acuan resin kering digunakan secara meluas pada masa
kini kerana penyelenggaraanya mudah dilakukan berbanding dengan alatubah minyak
direndam dan alatubah SF6. Dalam projek ini, kajian alatubah jenis acuan resin kering
dilakukan dengan memodelkan bahagian tubuh keratan di AutoCad. Model ini
digunakan untuk mengkaji pengagihan medan elektrik di penggulungan Voltan Tinggi
(HV). Analisis medan elektrik dilakukan menggunakan perisian Kaedah Elemen Finit
dimana dalam kajian ini ialah dengan menggunakan Comsol Multiphysics. Kajian ini
menumpukan pertukaran pengedaran medan elektrik apabila terjadi salah pada
penggulungan HV. Kesan salah aturan gulungan membawa kepada pembentukan
jurang udara di konduktor. Jurang udara mempunyai nilai medan elektrik kira-kira
7.16 x105 V / m. Simulasi untuk ideal dan ketidakbetulan gulungan dapat dijayakan
dan pengedaran medan elektrik telah direkodkan. Pengagihan medan elektrik telah
diplotkan dalam graf dimana graf untuk ideal dan misalignment dibincangkan.
Berdasarkan graf tersebut ia telah ditunjukkan bahawa kesan ketidakseimbangan
mempengaruhi tingkah laku bidang elektrik.

Cast resin dry type (CRDT) transformer is widely used nowadays as it is easy
maintenance compared to the oil immersed transformer and SF6 transformer. In this
project, the sectional core and winding of CRDT transformer was build using
AutoCad. This model is used to study the electric field distribution at the HV winding.
The electric field analysis is performed using Finite Element Method software whereas
in this study by using Comsol Multiphysics. The study focused change of the electric
field distribution when misalignment happened at the HV winding. This misalignment
was caused by the mishandling of the transformer and the lifetime of the transformer.
The effect of the misalignment leads to the formation of the air gap at the conductor.
The air gap had a maximum value of the electric field which approximately 7.16 x105
V/m. The simulation for ideal and misalignment was a success and the electric field
distribution was recorded. The electric field distribution was plotted in a graph and the
graph for ideal and misalignment was discussed. It is shown that the effect of
misalignment influenced electric field behaviour.
